›FIELD OF THE INVENTION

This invention pertains to compounds that inhibit protein kinases, compositions containing the compounds and methods of treating diseases using the compounds.

›BACKGROUND OF THE INVENTION

Numerous human diseases are characterized by increased and uncontrolled cell growth. This biology is driven, in many cases, by increased growth factor signaling. In addition, these pathologies often require an expanding blood supply and new vessel growth. Protein kinases are key components of both cell proliferation and endothelial cell expansion. Kinases are thus important targets for therapeutic intervention in pathologies characterized by uncontrolled cell growth.

Compounds

Geometric isomers may exist in the present compounds. Compounds of this invention may contain carbon-carbon double bonds or carbon-nitrogen double bonds in the E or Z configuration, wherein the term “E” represents higher order substituents on opposite sides of the carbon-carbon or carbon-nitrogen double bond and the term “Z” represents higher order substituents on the same side of the carbon-carbon or carbon-nitrogen double bond as determined by the Cahn-Ingold-Prelog Priority Rules. The compounds of this invention may also exist as a mixture of “E” and “Z” isomers. Substituents around a cycloalkyl or heterocycloalkyl are designated as being of cis or trans configuration. Furthermore, the invention contemplates the various isomers and mixtures thereof resulting from the disposal of substituents around an adamantane ring system. Two substituents around a single ring within an adamantane ring system are designated as being of Z or E relative configuration. For examples, see C. D. Jones, M. Kaselj, R. N. Salvatore, W. J. le Noble J. Org. Chem. 1998, 63, 2758-2760.

Compounds of this invention may contain asymmetrically substituted carbon atoms in the R or S configuration, in which the terms “R” and “S” are as defined by the IUPAC 1974 Recommendations for Section E, Fundamental Stereochemistry, Pure Appl. Chem. (1976) 45, 13-10. Compounds having asymmetrically substituted carbon atoms with equal amounts of R and S configurations are racemic at those carbon atoms. Atoms with an excess of one configuration over the other are assigned the configuration present in the higher amount, preferably an excess of about 85%-90%, more preferably an excess of about 95%-99%, and still more preferably an excess greater than about 99%. Accordingly, this invention includes racemic mixtures, relative and absolute stereoisomers, and mixtures of relative and absolute stereoisomers.

Compounds of this invention containing NH, C(O)OH, OH or SH moieties may have attached thereto prodrug-forming moieties. The prodrug-forming moieties are removed by metabolic processes and release the compounds having the freed hydroxyl, amino or carboxylic acid in vivo. Prodrugs are useful for adjusting such pharmacokinetic properties of the compounds as solubility and/or hydrophobicity, absorption in the gastrointestinal tract, bioavailability, tissue penetration, and rate of clearance.

Compounds of this invention can exist in an isotopic form containing one or more atoms having an atomic mass or mass number different from the atomic mass or mass number most abundantly found in nature. Isotopes of atoms such as hydrogen, carbon, phosphorous, sulfur fluorine, chlorine, and iodine include, but are not limited to, 2 H, 3 H, 14 C, 32 P, 35 S, 18 F, 36 Cl, and 125 I, respectively. Compounds that contain other isotopes of these and/or other atoms are within the scope of this invention. Compounds containing tritium ( 3 H) and 14 C radioisotopes are preferred in general for their ease in preparation and detectability for radiolabeled compounds. Isotopically labeled compounds of this invention can be prepared by the general methods well known to persons having ordinary skill in the art. Such isotopically labeled compounds can be conveniently prepared by carrying out the procedures disclosed in the Examples and Schemes herein by substituting a readily available isotopically labeled reagent for a non-isotopically labeled reagent.

A double-stranded siRNA (dsRNA) can have the same number of nucleotides on each strand (blunt ends) or asymmetric ends (overhangs). The overhang of 1-2 nucleotides can be present on the sense and/or the antisense strand, as well as present on the 5′- and/or the 3′-ends of a given strand

Multivalent binding proteins are binding proteins comprising two or more antigen binding sites. Multivalent binding proteins are engineered to have the three or more antigen binding sites and are generally not naturally occurring antibodies.

Specifically, 10 μL C-terminal GST-tagged, recombinant, human EGFR, amino acids 696-end containing the mutation L858R expressed by baculovirus in Sf21 cells (Millipore) was mixed with 10 ul inhibitor (various concentrations, 2% final DMSO) and 10 ul of ATP (50 μM final concentration) in reaction buffer (50 mM HEPES, pH 7.5, 10 mM MgCl 2 , 2 mM MnCl 2 , 0.1% BSA and 1 mM DTT, 40 μL final volume). The reaction was initiated by addition of 10 ul of biotinylated peptide substrate (Biotin-Ahx-AEEEYFFLFA, 0.5 μM final concentration) in a black 384-well plate (Packard). After 60 minutes incubation at room temperature, the reaction was quenched by addition 60 μL stop/revelation buffer to give 30 mM EDTA, 1 μg/ml streptavidin-APC (Prozyme), 50 ng/ml anti-phosphotyrosine mAb PT66-K Europium Cryptate, 30 mM HEPES, pH 7.5, 120 mM KF, 0.005% Tween-20, 0.05% BSA). The quenched reaction was allowed to stand at room temperature for 1 hour and then read in a time-resolved fluorescence detector (Envision, Perkin Elmer) at 615 nm and 665 nm simultaneously. The ratio between the signal of 615 nm and 665 nm was used in the calculation of the IC 50 .

To a 4 mL vial was charged EXAMPLE 4G (40 mg, 0.089 mmol) and tetrahydrofuran (2.2 mL). The resulting solution was treated with 1-methyl-1H-pyrazole-3-carbonyl chloride (14.2 mg, 0.098 mmol) and the reactions was stirred at ambient temperature for 16 hours. The reaction was treated with 0.1 mL methanol and concentrated. The concentrate was triturated with 2 mL ether and filtered to give the desired product as a hydrochloride salt.
